Integrated Two-Step Depolymerization and Electrocatalytic Upgrading of Lignin toward High-Yield Aromatic Monomers
Short Introductive summary
Lignocellulosic biomass, an abundant non-edible resource, is a promising alternative, comprising cellulose, hemicellulose, and lignin. Lignin, a carbon-rich aromatic polymer, is particularly challenging to valorize due to its complex and recalcitrant structure, consisting of various C-O (?-O-4, 4-O-5, ?-O-4) and C-C (?-?, ?-5, 5-5) linkages. Traditional lignin valorization methods, such as pyrolyis or organosolv, often result in undesirable recondensation, leading to low yields of aromatic monomers. To overcome this, reductive catalytic fractionation (RCF) has emerged, but batch RCF contaminates the valuable cellulose pulp with the catalyst, hindering downstream use. This study addresses these challenges by exploring and optimizing two advanced, decoupled strategies: an enhanced two-step catalytic hydrogenolysis and a sustainable electrocatalytic hydrogenolysis for the efficient conversion of lignin in birch wood to high-yield phenolic monomers and clean, recoverable glucan.
